Yan Shi, the head of the Chinese student association at Concordia University, where Lin was studying, told CTV that Lin's mother was extremely emotional and could not get through her words without constant tears.

"We come to take you home now," she said.

In the grisliest Montreal crime in years, police believe porn actor Luka Rocco Magnotta killed and dismembered Lin and posted a 10-minute video of it online. Montreal police Cmdr. Ian Lafreniere said the video shows Magnotta engaged in sexual acts involving body parts and also included evidence of cannibalism.

"We have been working extremely hard to find all the body parts with respect to the family," Lafreniere said.

Lin's left hand and foot were mailed to the headquarters of Canada's Conservative and Liberal parties in Ottawa. His right hand and foot showed up this week at two Vancouver schools.

Lafreniere told Vancouver radio station CKNW that Magnotta had spent time in Vancounver.

"Was it just passing by, or been there for a long time. We don't know," he said. "But we know he used to be in Vancouver, at least."

Montreal police are investigating a website that hosted Magnotta's chilling 10-minute video of Lin's murder. The site could face criminal charges for publishing obscene material.

Magnotta's name made headlines last week but he had already left disturbing trail in cyberspace.

Lafreniere said investigators plan to look into accusations by online animal rights activists that Magnotta killed kittens by suffocation or drowning and videotaped himself doing it.

There are also rumored links between the suspect and notorious killer Karla Homolka, arrested in 1993 for the rapes and murders of three Ontario girls, including her own sister. As part of a plea bargain, Homolka served 12 years in prison and was released a few years ago.

So far, Lafreniere said investigators have no evidence linking Magnotta to other crimes. But he remains the sole suspect in Lin's killing.

"Right now, we got no reason to believe there could be someone else involved in this horrible crime," Lafreniere said.
